We purchased these new and paid freight from the company when our daughter was breeding rabbits. Cage dimensions are 30x24x18. Selling in pairs. See website for specs. Comes with a galvanized feeder as well. $280 is for two stacked cages. $550 if you buy all four. These cages new with shipping are almost $800 so non negotiable on price.
